Minimal mutual coherence of discrete noiselets and Haar wavelets makes this pair of bases an essential choice for the measurement and compression matrices in compressed-sensing-based single-pixel detectors.

We introduce an efficient method for the reconstruction of the correlation between a compressively measured image and a phase-only filter.
